- 論文の詳細を見る
The present investigation was carried out in order to ascertain the effect of nitrogen on the quench-aging of steels containing 0.02〜0.03 and 0.15〜0.20 per cent carbon. The specimens tempered at 700℃ for 3 hours after quenching at 950℃ were requenched at 300〜700℃ after heating for 3 hours at respective temperatures and then aged at 30, 50 and 100℃. From the present investigation the following conclusions were obtained : (1) There is a distinct correlation between the nitrogen in steel and the quench-aging ; (2) By the addition of nitrogen stabilizer such as Al or Ti, or by the fusion in vacuum the aging due to nitrogen is reduced ; (3) The specimens containing less than 0.005 per cent of nitrogen revealed aging due to carbon.
